julia-venv seems not work for default conda environment?

[Hong-Xiang]

As discussed in pyjulia/#185, julia-venv works in some environment, and during recent tests, it seems that it works on virtual envs created by conda create -n <name>, and failed on default environment.

For virtual envs, it just works like a charm.
For default env, i.e. the environment without source activate <name, it get error:
ERROR: UndefVarError: Libdl not defined when

• runniing julia-venv-manage install-deps.
  or
• directly enter python repl, and

>>> from julia_venv import get_julia
>>> jl = get_julia()
ERROR: UndefVarError: Libdl not defined

This might be machine specific, I'm not sure if it only happens in my machine.

Indeed, it is only tested against non-root conda environment:

julia-venv/.travis.yml

Lines 46 to 50 in 578ef5c

	- source ~/miniconda/bin/activate test
	- julia-venv-manage install-deps
	- julia-venv-manage show
	- julia-venv -e "Base.banner(IOContext(stdout, :color => true))"
	- py.test --pyargs julia_venv

I'm not sure what's going on.

But I usually don't recommend using pip in root conda environment. Mixing two package managers is dangerous IMHO, especially when you are using a hacky package like julia-venv :)

Having said that, the output of julia-venv-manage show may tell you something useful.
